What kDa is lysozyme?
approximately 14 kDa
The molecular weight of lysozyme is approximately 14 kDa to 15 kDa and the isoelectric point is about pH 11 [33].
What can you detect with SDS-PAGE?
Protein separation by SDS-PAGE can be used to estimate relative molecular mass, to determine the relative abundance of major proteins in a sample, and to determine the distribution of proteins among fractions.
How does SDS-PAGE determine molecular weight?
Sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) is a reliable method for determining the molecular weight (MW) of an unknown protein. relative migration distance (Rf) is plotted, based on the values obtained for the bands in the MW standard.

What is the pI of lysozyme?
= 11.1
Because lysozyme has a very high pI (pI = 11.1), back-extraction of lysozyme in the AOT system requires that the aqueous phase have a at very high pH and high salt concentration.
How much lysozyme do I add?
We recommend using the lysozyme at a final concentration of 0.1-1 mg/ml. Higher concentrations of lysozyme will not improve lysis efficiency and may have an inhibitory effect.
Why do we use SDS-PAGE?
Sodium dodecyl-sulfate polyacrylamide gel electrophoresis (SDS-PAGE) is commonly used to obtain high resolution separation of complex mixtures of proteins. The method initially denatures the proteins that will undergo electrophoresis.
What does SDS-PAGE mean?
polyacrylamide gel electrophoresis
After exposure to SDS different proteins will have very similar charge to mass ratios because SDS coats the protein in a negative charge overwhelming whatever intrinsic charge the protein originally had. The acronym PAGE stands for polyacrylamide gel electrophoresis.
Is SDS-PAGE used for purification?
SDS-polyacrylamide gel electrophoresis (SDS-PAGE) transfer method was used for purification and enrichment of the protein from crude sample.
